Abstract
Abstract: Poorly differentiated pancreatic neuroendocrine carcinomas (pNECs) are rare, highly aggressive neoplasms. Frequently metastatic at diagnosis, prognosis is poor with median overall survival estimated to be less than 1 year. Although multidisciplinary management, including systemic medications and locoregional therapies aimed at reducing and preventing symptoms caused by mass effect, is the mainstay of treatment for patients with metastatic well-differentiated pancreatic neuroendocrine tumors, rapid progression, organ dysfunction, and poor performance status often preclude initiation of even single-modality palliative chemotherapy for patients with metastatic pNEC, limiting the use of and recommendation for multidisciplinary management.We describe the case of a 51-year-old male patient diagnosed with pNEC metastatic to liver and lymph nodes presenting with impending cholestatic liver failure for whom we were able to successfully initiate and dose-escalate cytotoxic chemotherapy with excellent radiographic response. After multidisciplinary review of his case, the patient underwent pancreaticoduodenectomy and hepatic wedge biopsies, with pathology demonstrating a pathologic complete response to chemotherapy in both the pancreas and liver. Surveillance scans at 2 years from initial diagnosis and 1 year from surgery remain without evidence of locoregional or distant recurrence, highlighting the importance and utility of multidisciplinary management in select cases.
期刊介绍:
Pancreas provides a central forum for communication of original works involving both basic and clinical research on the exocrine and endocrine pancreas and their interrelationships and consequences in disease states. This multidisciplinary, international journal covers the whole spectrum of basic sciences, etiology, prevention, pathophysiology, diagnosis, and surgical and medical management of pancreatic diseases, including cancer.
